Reads a 64-bit I/O port.
Reads the 64-bit I/O port specified by Port. The 64-bit read value is returned. This function must guarantee that all I/O read and write operations are serialized.
If 64-bit I/O port operations are not supported, then ASSERT(). If Port is not aligned on a 64-bit boundary, then ASSERT().
| Port | The I/O port to read. |
Writes a 64-bit I/O port.
Writes the 64-bit I/O port specified by Port with the value specified by Value and returns Value. This function must guarantee that all I/O read and write operations are serialized.
If 64-bit I/O port operations are not supported, then ASSERT(). If Port is not aligned on a 64-bit boundary, then ASSERT().
| Port | The I/O port to write. |
| Value | The value to write to the I/O port. |
Reads a 16-bit MMIO register.
Reads the 16-bit MMIO register specified by Address. The 16-bit read value is returned. This function must guarantee that all MMIO read and write operations are serialized.
If 16-bit MMIO register operations are not supported, then ASSERT(). If Address is not aligned on a 16-bit boundary, then ASSERT().
For Td guest TDVMCALL_MMIO is invoked to read MMIO registers.
| Address | The MMIO register to read. |
Reads a 32-bit MMIO register.
Reads the 32-bit MMIO register specified by Address. The 32-bit read value is returned. This function must guarantee that all MMIO read and write operations are serialized.
If 32-bit MMIO register operations are not supported, then ASSERT(). If Address is not aligned on a 32-bit boundary, then ASSERT().
For Td guest TDVMCALL_MMIO is invoked to read MMIO registers.
| Address | The MMIO register to read. |
Reads a 64-bit MMIO register.
Reads the 64-bit MMIO register specified by Address. The 64-bit read value is returned. This function must guarantee that all MMIO read and write operations are serialized.
If 64-bit MMIO register operations are not supported, then ASSERT(). If Address is not aligned on a 64-bit boundary, then ASSERT().
For Td guest TDVMCALL_MMIO is invoked to read MMIO registers.
| Address | The MMIO register to read. |
Reads an 8-bit MMIO register.
Reads the 8-bit MMIO register specified by Address. The 8-bit read value is returned. This function must guarantee that all MMIO read and write operations are serialized.
If 8-bit MMIO register operations are not supported, then ASSERT().
For Td guest TDVMCALL_MMIO is invoked to read MMIO registers.
| Address | The MMIO register to read. |
Writes a 16-bit MMIO register.
Writes the 16-bit MMIO register specified by Address with the value specified by Value and returns Value. This function must guarantee that all MMIO read and write operations are serialized.

| Address | The MMIO register to write. |
| Value | The value to write to the MMIO register. |
Writes a 32-bit MMIO register.
Writes the 32-bit MMIO register specified by Address with the value specified by Value and returns Value. This function must guarantee that all MMIO read and write operations are serialized.
